UNITED J .WILhIAM A. SUTTON, OF NEW YORK, N. Y.

I SKATE.

SPECIFICATION forming part of Letters Patent No. 236,276, dated January 4, 1881.

I Application filed December 3, 1879.

To all whom it ma@em:

Be it known that 1, WILLIAM A. SUTTON, of the city, county, and State of New York, have invented certain new and useful Improvements in Skates, of which the following is a specification.

In the accompanying drawings, Figure 1 represents a sectional side elevation of my improved skate; 2, a bottom view with parts broken away; and Fig. 3 a vertical transverse 2o clamps and the heel-clamp with auxiliary adjusting devices, by which, when the clamps are once set to the proper size of shoe, the quick and rigid attachment of the skate to the sole and heel is obtained, as will appear more fully 2 5 hereinafter.

Referring to the drawings, A represents a skate; B, the sole-plate, and O the heel-plate, of the same.

The sole-plate B is provided with trans- 3o versely-sliding sole-clam ps D, which arejointly moved by a right-and-left-hand screw, D,that connects the guide-plates D of the clamps in the well-known manner. The guide-plates D slide by means of slots tr and fixed pins or 5 studs a, with enlarged heads, at the under side of the sole-plate.

The heel -plate 0 is provided with fixed clamps or checks E and an adjustable clamp, E, which is guided in the slotted heel-plateO and set to the heel by a screw, E

The skates of this construction are attached to the sole and heel of the boot or shoe by means of a key, which is applied to the square ends of the set-screws D and E the set-screws 4 5 requiring for the rigid connection of the skate and shoe the application of considerable power, especially when after some use the parts should get rusty. To avoid this objection and facilitate the application of the skate so as to be easier handled, even by ladies, one of the soleclamps D and the heel-clamp E are provided with auxiliary adjusting devices, by which these clamps are made independent and separately movable on their respective guide-plates, and actuated, after adjustment by the setscrews, by independent cam-levers F F. For this purpose one of the sole-clamps and the heel-clamp are arranged with shanks b b, which are guided by slots and pins on the main guideplates. The cant-levers F F are eccentrically pivoted, the eam-leverF of the sole-clamp being connected hya circular slot, d, to the stud d of the shank b of the movable sole-clamp D, while the cam-lever F of the heel-clamp is pivoted to the fixed stud eof the main guide-plate e of the heel-clamp E, and arranged to engage with its cam the raised clamp portion E and a fixed stud, 6 on the shank b of the heel-clamp, so as to govern the forward and backward motion of the heel-clamp. This camlever connection may, however, be also made in a different manner, provided that one of the sole-clamps and the heel-clamp obtain their final adjustment to the sole and heel by the auxiliary lever devices.

The auxiliary adjusting mechanism has the advantage that the clamps may be set once for all to the size of the shoe, so as to require no adjustment when the skate is put on, while the final clamping action is imparted by throwing the cam-levers into the longitudinal position of the skate, as shown in Fig. 1, which can be accomplished without the least diffi- I culty, so that an almost instant and positive attachment of the skate to the boot or shoe is obtained.

Having thus described my invention,I claim as new and desire to secure by Letters Patcut- 1. In a skate provided with adjustable sole and heel clamps, the combination of the adjustable guide-plate D with a sliding soleclamp, D, guided thereby, and with a cam-1e ver, F, pivoted to the guide-plate and connected to the shank of the sole-clamp, so as to produce the final adjustment of the sole clamp, substantially as set forth.

The combination, in a skate, of a heelclamp consisting of two parts connected and adapted to move together and independently mmthzk of each other, and both movable on the heelmy inventhhg sigveqmyname, -P plate 0, an adjusting device supported by the ence of two witnesses, thls 20th day of Novemheel-plate to bear upon one part of said clamp, ber, 1879.
